I think its too tight, which is also why changing gears is much harder now, but I'm still a newbie in this so I'll wait for more input.
The right looking at it from where? The Back of the bike? the side?
Many riders check the tire pressure with a gauge before every ride. A gauge is probably a good investment. They are not very expensive. After a while you can tell what's good enough, just by squeezing the tire.
Do you live in a location that gets very cold in winter? This can effect the battery, tires, and grease.
